Shōsō Inkstone

Inkstone carving

Inkstones are used in brush calligraphy to grind the ink for writing characters. Inkstones are highly valued writing tools, and the process of ink grinding is regarded as a calming practice preceding calligraphic activities. First, the rough shape of the inkstone is cut out of the base rock. Next, a long-handled chisel is used to cut a flat surface where the ink will be ground and a well where the ink will gather. The final form is coated with a finish of wax or lacquer. Popular varieties of stone include Amehata slate (amehataishi) from Yamanashi prefecture, akamaishi schalstein from Yamaguchi prefecture, and hōmeiseki shale and slate from Aichi prefecture.
